In this paper we would like to introduce design of a system for controlling a PC by eye movements. During last ten years the computers have become common tools of work – it is nearly impossible to exist without them in everyday life. We are witnessing the time of revolutionary introduction of computers and information technologies into daily practice. Healthy people use keyboard, mouse, trackball, or touchpad for controlling the PC. However these peripheries are usually not suitable for disabled people. They may have problems using these standard peripheries, for example when they suffer from myopathy, or cannot make moves with hands after an injury. Therefore we are coming with a proposal how to ease the disabled people to control the PC.
